I'm trying to make fileutils-3.4 on a sun3, running sunos4.0.3.
Here's what happened:

for dir in lib src man; do echo making all in $dir; cd $dir; make bindir='/usr/local/gnu/bin' libdir='/usr/local/gnu/lib' mandir='/usr/local/gnu/man/man1' manext='1' binprefix='' manprefix='g' LIBS='' LIBPROGS='' AR='ar' RANLIB='ranlib' DEFS='-DHAVE_LIMITS_H=1 -DDIRENT=1 -DMOUNTED_GETMNTENT1=1 -DSTAT_STATFS2_BSIZE=1 -DHAVE_UNISTD_H=1 -DHAVE_FTIME=1 -DHAVE_MKFIFO=1 -DHAVE_FTRUNCATE=1 -DHAVE_VPRINTF=1 -DHAVE_ALLOCA_H=1 -DHAVE_ST_BLOCKS=1 -DHAVE_UTIME_NULL=1' CFLAGS='-g' LDFLAGS='-g' LIBS='' CC='gcc -O' all; 
cd ..; done

In file included from getdate.c:76:

Can you help?
Thanks for your time
